【摘要】：类金刚石薄膜(DLC)具有十分优异的减摩耐磨性能,是一种极具发展潜力的固体润滑材料。但其摩擦学性能受到很多因素的影响,这些因素主要可以分为两大类:固有因素和外在因素。在不同的固有因素和外界因素影响下DLC薄膜的摩擦学性能会产生较大差异,这大大制约了人们对其摩擦学行为及摩擦机理的认识,限制了其应用范围的扩展。总结了目前有关DLC薄膜摩擦机理的三种理论,即转移膜理论、滑行界面石墨化理论和化学吸附钝化悬键理论,并在此基础上概括分析了各固有因素和外界因素对DLC薄膜摩擦学性能的影响及其机理,提出未来可以从基础理论和相关技术两方面对DLC薄膜的摩擦学性能展开深入研究。
[Abstract]:Diamond film (DLC) has excellent properties of antifriction and wear resistance, is a kind of solid lubricating material has great potential for development. But its tribological properties are influenced by many factors, these factors can be divided into two main categories: intrinsic and external factors. The tribological properties of different natural factors and external factors the DLC film will have great differences, which greatly restricts the understanding of the tribological behavior and friction mechanism, expand the limits of its scope of application. The related theory summarizes three kinds of DLC film friction mechanism, namely the transfer film theory, sliding interface theory of graphitization and chemical adsorption theory and passivation of dangling bonds. Based on the summary analysis of the effect on the tribological properties of DLC thin films by the inherent factors and external factors and mechanism, put forward from the basic theory and related technology of the two party in DLC films The tribological properties are studied in depth.
